Radiotherapy

Hi Linziiloo. Welcome to the community. It’s good that you’ve come here to ask. Other people’s experiences at least give you an idea of what to expect. 
I had 6 weeks of RT. I had little to speak of for the first two weeks but by the end of the third week I needed help from my husband physically but more importantly mentally. 
What you can do is be there, run errands, walk the dog, listen to her, give her hugs, cuddles and hold her hand.  That sort of thing. 
Does your sister have a partner? 
What you can do really depend on whether she lives on her own or not. 
Radiotherapy is not a walk in the park but it’s doable. 
I am almost four years clear. 
Stay with us. I and others will have lots of suggestions once we know a little more 

Hi  As Dani has said it’s hard but doable I was 61 when diagnosed now over 4.5 years post radiotherapy and chemotherapy for HPV SCC tonsil cancer with 7 lymph nides. Ask questions on here or see if your sister wants to join for support as well.

Just be there. My sister, sons and daughter in law have been my rocks.  I needed a lot of support after week 3.  I am now 12cweeks post treatment and I still have some very dark days.  It's a truly gruelling treatment but people around, just being there makes it all possible to get through.  

I also am having Macmillan Counselling support.  Helps to offload to somebody who doesn't know you. Session often ended in tears but it does help, it's the only time I've really cried.  Tell her to join the Forum it's really good to know you are not alone.

Don't underestimate the value of sisters, family and friends.......so important.

I too felt anxious and when lying there I thought I can't do this. But on the next time the waiting room was full bof people just like me. So I asked them as a group. "How have you coped"? And they said you just get through, hang in there. You will get through it. They've been doing this for years. 

You will manage it as we all have. Think positive and follow us
